Name a common symptom of attention-deficit/hyperactivity disorder (ADHD).

• A. Impulsivity
• B. Excessive reading ability
• C. Social withdrawal
• D. High academic achievement

Answer: (A)

Impulsivity is a hallmark symptom of attention-deficit/hyperactivity disorder (ADHD). Individuals with ADHD often exhibit behaviors that show a lack of forethought or consideration of the consequences of their actions. This can manifest as trouble waiting for their turn, blurting out answers in conversations, or making hasty decisions without thinking through potential risks or outcomes. Impulsivity can significantly impact a person's social relationships, academic performance, and general functioning because it may lead to disruptive behaviors or interpersonal conflicts.

In contrast, the other options mentioned do not align with the typical symptoms seen in ADHD. While excessive reading ability and high academic achievement may be characteristics of some students, they are not symptoms associated with ADHD. Similarly, social withdrawal is not a defining feature of ADHD, as individuals with this condition can often be socially active, although they may struggle with interactions due to impulsivity or hyperactivity. Therefore, recognizing impulsivity as a common symptom of ADHD helps in identifying and understanding this complex disorder.
